The excise tax levied on low-point beer under Section 163.3 of this title shall be paid by the following:
When the sale is made by a manufacturer located outside of the state and doing business in this state by virtue of and under permit issued as hereinafter provided to a wholesaler located and doing business in this state, the tax shall be paid by the wholesaler.
When the sale is made by a manufacturer located and doing business in this state to a retail dealer located and doing business in this state, the tax shall be paid by the manufacturer, who must also be the holder of an effective wholesale beverage dealer's license. Before making any such sale to a retail dealer the manufacturer must apply for and procure a license as a wholesaler, provided for in Section 163.1 et seq. of this title.
When the sale is made by a manufacturer located and doing business in this state to a consumer in this state, the tax shall be paid by the manufacturer;
When the sale is made by a wholesaler, located and doing business outside this state, and who has obtained an Oklahoma wholesale beverage dealer's license, to a retail dealer located and doing business in this state, the wholesaler shall be liable for and must pay to the Tax Commission the beverage tax due on such sales. In the event of a retail dealer, doing business in this state, purchases beverage from a wholesaler doing business outside this state, and who does not have an Oklahoma wholesale beverage dealer's license, the retailer shall be liable for and must pay to the Oklahoma Tax Commission the tax due on such sales. Both the wholesalers and retailers liable for the payment of such tax shall, on forms prescribed by the Tax Commission, report to the Tax Commission such sales and deliveries.
For the purpose of collecting and remitting the tax imposed under Section 163.1 et seq. of this title, the wholesaler collecting such tax is hereby declared to be the agent of the state for such purposes; and
Except as provided in paragraph 1 of Section 163.7 of this title, no retail dealer may sell any low-point beer except at retail, for consumption or use; and no retail dealer may have in his or her possession, or offer for sale, any such beverage upon which the tax shall not have been paid.
